Doppler velocity log systems when  fitted to an ROV, AUV or diver, provide information about the motion of the vehicle or diver relative to the seabed. 

DVL data can be used by a vehicle’s systems or diver’s equipment to:

  • keep an ROV or AUV stationary relative to the seabed
  • provide a diver with information about their motion relative to the seabed
  • update a vehicle or diver’s dead-reckoning navigation system
  • significantly improve the accuracy of a vehicle or diver’s acoustic tracking or inertial navigation system

SOSub currently supply and support the Waterlinked A50 DVL.
